Weather in December
Temperature
The arrival of December suggests a slight decrease in the average high-temperature, moving from a hot 33°C (91.4°F) in November to a moderately hot 29.8°C (85.6°F). During December, Dégrad Laurens experiences a consistent low-temperature average of 22°C (71.6°F).Heat index
December's average heat index is estimated at a very hot 39°C (102.2°F). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.Take into consideration that the heat index values are calculated for shade and light wind conditions. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'real feel', ties air temperature with relative humidity to produce the perceived temperature sensation. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
